I just got Simons' Basic, and so far it is a disappointment!  The
specific problem I have is that commands that write to the screen,
e.g. LIST (with or without PAGE), DISPLAY, TRACE, DUMP, frequently
(not always) zap the screen, as if they had triggered a RUN/STOP
and RESTORE.  This happens after printing on screen anywhere from
part of a line to dozens of lines.  Sometimes it doesn't happen at
all.  And sometimes these commands hang the computer instead,
either before or after clearing the screen.

I have an early model 64, circa 12/82.  Is SB incompatiable with its
ROM?  Is there something I can POKE to override the incompatibility
(if that's what it is)?  Or do I have a bad copy of SB that should
be returned?

By the way, it took me a long time to get SB, with a series of
promises, back orders, etc. from mail order houses.  One told me,
after a long back order, that CBM had raised the price to $45 and
they weren't filling any orders until the purchaser reordered at
some higher price than previously advertised.  At that point (some
weeks ago) Protecto was advertising it at about $25, and they
claimed to have it in stock, so I ordered from them.  At about the
time I expected delivery, I got an out-of-stock back order notice.
However, without further action on my part, Protecto delivered
about a week or 10 days later, and at the advertised price.

Replies by mail please -- if there is information of general interest,
I will summaraize to the net.  Thanks.
